Rachel Berney and Jeff Hou contribute to new book on social justice in urban design

“Just Urban Design: The Struggle for a Public City” (MIT Press 2022) features a collection of chapters and case studies that apply a social justice lens to the design of urban environments. Sixteen contributors, including Rachel Berney of Urban Design & Planning and Jeff Hou of Landscape Architecture, examine topics ranging from single-family zoning and community capacity building to immigrant street vendors and the right to walk. The book is open-access and can be downloaded from MIT Press here.

Performative By-Products: The Emergence of Waste Reuse Strategies at the Blue Lagoon

Abstract

Materials and landscapes associated with waste are perceived as objectionable. By reactivating and embracing waste conditions as desirable opportunities for diverse programmes rooted in economy, ecology, and culture, designers can form hybrid assemblages on waste sites through the exchange of waste materials—a landscape lifecycles approach. This frame-work is applicable to not only design research, but also as a critical lens for evaluating the landscape performance of existing projects that engage with waste reuse. The Blue Lagoon in southwest Iceland materialized as a spa industry out of geothermal waste effluent from the adjacent Svartsengi Geothermal Power Station, reusing undesirable materials and transforming a waste landscape through diversified material recovery strategies. Featuring an industrial by-product turned economic generator, this case study reveals the opportunities for reusing geothermal ‘waste’ in these emergent landscape conditions, which hybridize economies with recreation, research, and ecology, and shift the conventional relationship with waste from passive to performative.

Abstract

Urban overheating significantly affects people's physical and mental health. The addition of street trees is an essential, economical, and effective means by which to mitigate urban heat and optimize the overall thermal environment. Focusing on typical street canyon clusters in Harbin, China, landscape morphology was quantified by streetscape interface measurements (sky view factor, tree view factor, and building view factor). Through ENVI-met simulations, the correlation mechanism between streetscape interface measurements and thermal environment was evaluated, and optimization methods for assessing the thermal environment of urban streets were proposed. The results revealed: (1) The thermal environment optimization efficiency of general street canyon types was greatest when street tree spacing was 12 m. At present, the smaller spacing has not been simulated and may yield better thermal environment results. The average decrease in temperature (Ta), relative humidity (RH) and mean radiant temperature (MRT) was 0.78%, 2.23%, and 30.20%, respectively. (2) Specific street canyon types should adopt precise control strategies of streetscape interface according to their types to achieve the optimal balance between thermal environment optimization and cost. (3) Streetscape interface measurements and thermal environment indexes show quadratic correlation characteristics, and are critical points for further investigation. The conclusions are more specific than previous research findings, which are of great significance for decreasing the urban heat island effect at the block scale, improving residents' physical and mental health, and improving the urban environment quality.

Celina Balderas Guzmán

Celina Balderas Guzmán, PhD, is Assistant Professor in the Department of Landscape Architecture. Dr. Balderas’ research spans environmental planning, design, and science and focuses on climate adaptation to sea level rise on the coast and urban stormwater inland. On the coast, her work demonstrates specific ways that the climate adaptation actions of humans and adaptation of ecosystems are interdependent. Her work explores how these interdependencies can be maladaptive by shifting vulnerabilities to other humans or non-humans, or synergistic. Using ecological modeling, she has explored these interdependencies focusing on coastal wetlands as nature-based solutions. Her work informs cross-sectoral adaptation planning at a regional scale.

Inland, Dr. Balderas studies urban stormwater through a social-ecological lens. Using data science and case studies, her work investigates the relationship between stormwater pollution and the social, urban form, and land cover characteristics of watersheds. In past research, she developed new typologies of stormwater wetlands based on lab testing in collaboration with environmental engineers. The designs closely integrated hydraulic performance, ecological potential, and recreational opportunities into one form.

Her research has been funded by major institutions such as the National Science Foundation, National Socio-Environmental Synthesis Center, UC Berkeley, and the MIT Abdul Latif Jameel Water and Food Systems Lab. She has a PhD in the Department of Landscape Architecture and Environmental Planning from the University of California, Berkeley. Previously, she obtained masters degrees in urban planning and urban design, as well as an undergraduate degree in architecture all from MIT.

College of Built Environments’ Research Restart Fund Awards Four Grants in First of Two Cycles

The College of Built Environments launched a funding opportunity for those whose research has been affected by the ongoing pandemic. The Research Restart Fund, with awards up to $5,000, has awarded 4 grants in its first of two cycles. A grant was awarded to Real Estate faculty member Arthur Acolin, who is partnering with the City of Seattle’s Office of Planning and Community Development to understand barriers that homeowners, particularly those with lower incomes, face to building Accessory Dwelling Units…

Landscapes of Industrial Excess: A Thick Sections Approach to Gas Works Park

Abstract

Gas Works Park in Seattle, WA, designed by Richard Haag Associates and recently listed on the National Register of Historic Landmarks, serves as one of the earliest post-industrial sites to be transformed into a public park through remediation and reclamation. The radical nature of the park lies in its adaptive reuse of waste landscapes, not merely ameliorating contaminated land but transforming it to serve the public. Although officials and residents called for the remains of the industrial plant to be removed, Haag convinced the public to retain elements of the industrial apparatus and, more importantly, to retain and treat the polluted soils. Previous scholarship focuses primarily on the architectural elements, leaving the landscape as mere setting. This article proposes a site narrative as read through the landform. It suggests an alternative reading that gives voice to the site's toxic history.
